A new class of rhodamine luminophores: Design, syntheses and aggregation-induced emission enhancement
A new class of rhodamine luminophores, 3′,3″- bis(oxospiroisobenzofuran)-3,7-bis(dialkylamino)benzopyrano-xanthene derivatives (ABPX), have been successfully developed. The emission behavior of ABPX series is directly opposite to the concentration quenching of conventional rhodamine dyes. ABPX series exhibit aggregation-induced emission enhancement (AIEE).
